With one exception none of them was ever sub- mitted for publication. The exception is the translation of a section of al-Maybud¯ı’s commentary on al-Abhar¯ı’s Hid¯ayatal-H. ikmah, which was accepted in 1993 for publication in the third volume of An Anthology of Philosophy in Persia, edited by Mehdi Amin Razavi. Only the first two volumes of that work were published. Nicholas Heer Seattle, Washington 5 A LECTURE ON ISLAMIC PHILOSOPHY I. Arabic Translations of Greek Works. As is well known, the Islamic state, which the prophet Muh. ammad had founded in Mad¯ınah in the 7th century A.D., expanded very rapidly in the following years, so that by the middle of the 8th century we find Muslims in control of the lands stretching all the way from Spain in the West to the borders of India in the East. Less well known perhaps is that the Christian scholars of those conquered areas, particularly in Syria and Iraq, had for some time been students of Greek philoso- phy and science and had translated many Greek works into Syriac, which was the language they were using at the time of the Muslim conquests. Later during the ninth century, at the command of the Muslim caliphs, they translated these Greek works from Syriac into Arabic and often directly from Greek into Arabic. Among the Greek works which they translated during this period were all the works of Aristotle with the exception of his Politics, Plato’s Timaeus, Republic, and Laws, and various works of such Neoplatonists as Proclus, Porphyry, Plotinus, and oth- ers. It is through these translations from Greek into Arabic that Muslims became acquainted with Greek philosophical thought.1 II. Some Famous Muslim Philosophers. What we call Islamic or Arabic philosophy is then a continuation and revival of the late Greek philosophical tradition undertaken by people who considered them- selves Muslims and who wrote in Arabic instead of Greek and Syriac. Let me mention a few of the most famous of these Muslim philosophers. The first Muslim philosopher of note was al-Kind¯ı.He was of Arab descent and died sometime before 870 A.D. Next was al-R¯az¯ı(Rhazes), who died about 925 or 935 A.D. and was known for his rejection of revealed religion. Al-F¯ar¯ab¯ı,who died in 950 A.D. was of Turkish descent and was known among Muslims as the “second teacher,” Aristotle being the first. He was most famous for his works on political theory. Ibn S¯ın¯a(Avicenna), who died in 1037 A.D., was without doubt the most influential of all the Muslim philosophers on the later development of Islamic philosophy and theology. Ibn Rushd (Averroes), a Spaniard who died in 1198 A.D., was known mainly for his commentaries on Aristotle. Finally, al-T. ¯us¯ı, who died in 1273 A.D., although not as well known in the West as the previous philosophers mentioned, was nevertheless very influential in the later development of Islamic philosophy and theology.2 1 For more information on the translations of Greek works into Arabic see Moritz Steinschneider, Die arabischen Ubersetzungen¨ aus dem Griechischen, Graz, 1960; ‘Abdurrah. m¯anBadawi, La Transmission de la philosophie grecque au monde arabe, Paris, 1968; and Richard Walzer, Greek into Arabic, Oxford, 1962. 2 Further information on each of these philosophers may be found in the Ency- 7 Perhaps I should point out here that many of the works of these Muslim philoso- phers were later translated into Latin and Hebrew and had a profound influence on the development of philosophy among Christians and Jews.3 Let me now turn to the basic ideas and doctrines which were common to most of the Muslim philosophers without, however, going into any of the differences of opinion which may have existed between individual philosophers. III. The Divisions of Philosophy. It should be noted, first of all, that Islamic philosophy covered a much wider range of subjects than we would consider to be included within philosophy today. According to al-Khuw¯arizm¯ı, a tenth century encyclopaedist, philosophy was di- vided into two major branches: theoretical and practical. Each of these branches in turn consisted of three subdivisions. Thus theoretical philosophy was made up of (1) metaphysics or theology, which dealt with non-material things, (2) mathematics, which had to do with both non-material and material things, and included arith- metic, geometry, astronomy, music, and mechanics, and (3) physics, which dealt with material things, and included such sciences as medicine, meteorology, miner- alogy, botany, zoology, chemistry, and finally psychology or the science of the soul. The three subdivisions of practical philosophy were (1) ethics, that is, individual or personal ethics, (2) economics, which in those days meant household or family ethics, and (3) politics, which could be said to be the ethics of the city or the state. Logic, which was the basis for all of these sciences, both theoretical and practical, was sometimes considered a third major branch of philosophy.4 A much simpler division of philosophy into six main categories is given by al- Ghaz¯al¯ı,an eleventh century theologian who studied philosophy and later wrote a book attacking many of its doctrines. In al-Munqidh min al-D. al¯al, or Deliverance from Error, al-Ghaz¯al¯ıdivides philosophy into mathematics, logic, physics, theology or metaphysics, politics, and ethics.5 clopaedia of Islam, new edition, Leiden, 1960-2004.

Montgomery Watt in The Faith and Practice of al- Ghaz¯al¯ı, London, 1953, pp. 33-38.

I shall also have something to say about physics and especially psychology, which, as I have mentioned, was considered a subdivision of physics. IV. The Proof for the Existence of a First Cause. Works on metaphysics usually begin with a proof for the existence of a First Cause or Necessarily Existent Being. To prove the existence of this First Cause, the philosophers divided existence into three categories: (1) necessary existence, which is predicated of that which does not need a cause for its existence, (2) possible or contingent existence, which is predicated of things which can conceivably either exist or not exist, but which must have a cause if they are to exist, and (3) impossible existence, which is predicated of things whose existence would involve a logical contradiction. The philosophers then argued that since some possible or contingent things are known to exist, these must have causes which have brought them into existence. If these causes are also possible or contingent, they in turn must have causes. However, since both an endless chain of causes and a circular string of causes were considered by the philosphers to be impossible, any series of causes and effects must end with a first cause that itself does not have a cause for its existence.
